InfoWorldMike writes: "Update to New Controversy over Black Hat Presentation: A planned demo on RFID security by a security researcher has been pulled from this week's Black Hat Federal security conference after security card maker HID claimed the talk violated the company's patent rights and threatened to take legal action against Chris Paget, the researcher, and IOActive, Paget's employer, if the talk went forward, InfoWorld reports. The company decided to cancel the talk after all-night negotiations with HID collapsed, said Josh Pennell, CEO of IOActive. In response, Black Hat organizers were forced to tear materials out of printed show proceedings and will instead present a discussion by a representative of the ACLU on the criticality of RFID security, said Jeff Moss, founder and director of Black Hat."
